Thread: Whats ur TP with the car off "key on"???

My TP with the car off key on says "33", which seems high. I'm not sure what it should be or if it makes a difference.

Example if you bring up a map, the map trace is almost half way across the table :numbness:

Where does the TP amount come from when the car is off, "key on"

I was thinking i was having issues with my MAF sensor.

some info

.75v with the car off. I tried another maf and it was .65v. I checked TP and it was still "33"

When idling my TP is very low 20's and i think its on the second column (idle is set at 1,000rpm) because of large cams. Thus the MAF value is a bit higher, which bumps me over to the second column.

TP is dependent on K value. You can reduce it by reducing the K value and compensating with the Current injector size.

It doesn't make any difference because the engine isn't running. TP=KxQ/N where N=RPM. When the engine isn't running, RPM=0 and since dividing by zero is undefined (and causes a CPU error), RPM is arbitrarily initialized to 100. This means at the same Q, TP will be 1/10th the initial value at 1000 rpm.
